47127 针对随机森林（RF, random forest）算法的投票原则无法区分强分类器与弱分类器差异的缺陷，提出一种加权投票改进方法，在此基础上，提出一种检测 Android 恶意软件的改进随机森林分类模型（IRFCM, improvedrandom forest classification model）。 Aiming at the defect of vote principle in random forest algorithm which is incapable of distinguishing the dif-ferences between strong classifier and weak classifier, a weighted voting improved method was proposed, and an im-proved random forest classification (IRFCM) was proposed to detect Android malware on the basis of this method.
47128 IRFCM 选取 AndroidManifest.xml 文件中的 Permission 信息和 Intent 信息作为特征属性并进行优化选择，然后应用该模型对最终生成的特征向量进行检测分类。 TheIRFCM chose Permission information and Intent information as attribute features from Android Manifest.xml files andoptimized them, then applied the model to classify the final feature vectors.
47129 Weka 环境下的实验结果表明IRFCM 具有较好的分类精度和分类效率。 The experimental results in Weka environ-ment show that IRFCM has better classification accuracy and classification efficiency.
